Understanding In-vehicle eCall Systems

With the deployment of European eCall in 2015, development of In‑vehicle eCall Systems (IVS) is in full swing. The correct choice of components will have a large affect on time‑to‑market. Important factors to consider are the possibility to verify IVS designs before eCall is deployed, the ability to support design‑in requirements of closely‑coupled GPS and GSM subsystems, comprehensive software support, component‑level certification of the GSM modem, forward compatibility with future wireless technologies, and the availability of automotive‑grade GPS and GSM components in high‑volume. This paper examines these requirements.
